cholesterols, plural;
  1. A compound of the sterol type found in most body tissues, including the blood and the nerves. Cholesterol and its derivatives are important constituents of cell membranes and precursors of other steroid compounds, but high concentrations in the blood (mainly derived from animal fats in the diet) are thought to promote atherosclerosis


  1. an animal sterol that is normally synthesized by the liver; the most abundant steroid in animal tissues
  2. Cholesterol is a waxy steroid metabolite found in the cell membranes and transported in the blood plasma of all animals. It is an essential structural component of mammalian cell membranes, where it is required to establish proper membrane permeability and fluidity. ...
  3. A sterol lipid synthesized by the liver and transported in the bloodstream to the membranes of all animal cells; it plays a central role in many biochemical processes and, as a lipoprotein that coats the walls of blood vessels, is associated with cardiovascular disease
  4. A waxy, fatty substance found in tissues throughout the body. Certain types of cholesterol circulating in the bloodstream can accumulate in blood vessels, blocking normal blood flow, and leading to heart attack and other circulatory complications.
  5. a substance normally made by the body, but also found in foods from animal sources, like beef, eggs, and butter. Too much cholesterol in the body can lead to narrowing and blockage of the arteries, especially those that feed the heart and keep it healthy. ...
  6. A fatlike substance contained in almost every cell of the body. In the blood it exists in two forms, known as free and esterified. The latter form is under certain conditions deposited in the inner lining of the arteries (see arteriosclerosis). ...
  7. Substance manufactured by the liver and other organs and consumed via animal fat. High-fat diets increase the amount made. It is believed that high levels lead to collection of cholesterol in the arteries, possibly leading to serious health risks.
  8. a waxy substance, produced naturally by the liver and also found in foods, that circulates in the blood and helps maintain tissues and cell membranes. Excess cholesterol in the body can contribute to atherosclerosis and high blood pressure.
  9. The barrier function of skin depends on the stratum corneum extracellular lipid matrix, which includes ceramides, cholesterol, and free fatty acids. Smaller amounts of cholesterol sulfate and cholesteryl oleate may be present. ...
  10. Is used to help repair the skin’s lipid barrier.
  11. a type of fat produced by the liver and found in the blood; it is also found in some foods. Cholesterol is used by the body to make hormones and build cell walls.
  12. A soft, fat-like substance found naturally in the body.
  13. A fat-soluble substance present in the blood and in animal fats that facilitates absorption and transport of fatty acids, and is necessary in hormone production. High levels of blood cholesterol have been linked to atherosclerosis and heart disease. See high and low density lipoprotein cholesterols.
  14. What it's good for: Makes cell membranes, hormones. Low-density lipoprotein (LDL) is often called "bad" cholesterol because too much in your blood can cause heart disease. High-density lipoprotein (HDL) is often called "good" cholesterol because it helps remove LDL . ...
  15. Cholesterol is a soft, waxy substance present in all parts of the body including the nervous system, skin, muscles, liver, intestines, and heart. It is both made by the body and obtained from animal products in the diet. ...
  16. A fat-like substance found in blood, muscle, liver, brain, and other tissues in people and animals. The body makes and needs some cholesterol. Too much cholesterol, however, may cause fat to build up in the artery walls and cause a disease that slows or stops the flow of blood. ...
  17. a fatty substance found in animals that performs many vital functions and is synthesized by the liver and the adrenal cortex.
  18. A fat-like substance that is made by the body and is found naturally in animal foods such as meat, fish, poultry, eggs, and dairy products. Foods high in cholesterol include liver and organ meats, egg yolks, and dairy fats. Cholesterol is carried in the blood. ...
  19. a waxy substance that is produced in the human body, animal fats, and in dairy products and is transported in the blood.
  20. The level of cholesterol in one's blood is an important measure of the state of one's health, especially in terms of assessing life expectancy. Unfortunately, 2 different ways of measuring it are used. ...
  21. A long chain molecule that is absorbed from food in the intestine or produced in the liver. It is needed as a part of blood plasma and of cell membranes.
  22. A sterol present in all animal tissues. Free cholesterol is a component of cell membranes and serves as a precursor for steroid hormones, including estrogen, testosterone, aldosterone, and bile acids. ...
  23. Used as a emulsifier and lubricant in eye creams, shampoo's and other cosmetic products.
  24. a steroid-based molecule found in many foods; high cholesterol levels are seen in correlation with a variety of health problems.
  25. A waxy substance that the body uses to synthesize steroid hormones (sex hormones, coristol, etc.). When present in excessive quantities in the blood, it increases the risk of heart disease. Cholesterol can be reduced through exercise and careful diet if thyroid hormone levels are normal.
